Plague-infected Prairie dogs have caused a shut down in parts of a city and wildlife area near Denver. Sections of the Rocky Mountain Arsenal National Wildlife Refuge were closed in late July as a precautionary measure after the plague was discovered, according to the US Fish and WIldlife Service.
Unaffected refuge areas were reopened on Saturday, but a suburb north of Denver, will remain closed until Labor Day weekend, the Health Department said.
“The prairie dog colonies are being monitored and burrows are being treated with insecticide, but there is still evidence of fleas in the hiking and camping areas, which could put people and pets at risk, so those areas will remain closed,” said John M. Douglas, Jr., the Executive Director of Tri-County Health Department.
There have been no infections in humans reported, Douglas said.
